The rate or speed of thermal energy transfer is ...................... when the temperature difference between the hot place and cold place decreases.

• faster

• slower

• the same

Energy is always ​ (a)   , so the thermal energy has not been ​created or ​ (b)   , it has just ​ (c)   to a different place.

• conserved
• destroyed
• dissipated
• changed
